22 arc subsonic load????

[Eric Leonard]

Anybody got one for any of the heavier bullets,, have a bolt gun with a 7 twist and a suppressor and would like to try some subsonic ammo.

I used to load the 223 with blue dot and 69 Sierras down to 1000 fps with surprisingly good accuracy and I think it would work in the 22 ARC but haven’t seen anything in print.

Trail boss if you have some on hand.
Hodgdon has sub loads listed for 223. They use Tightgroup w/ 55-77 gr bullets and also Clays w/ 55 gr bullets.

I ain’t got any TB , I may try starting with my 223 blue dot load and see if I can make it work ,
With the 223 I started at 15 grs blue dot and worked down until I got subsonic with the 69s and it shoots good.

Vit N32C also works well. I’ve loaded 88gr 223 subs, I was just under 5 gr with Trailboss. I’d start at ~6gr in the ARC and go from there.

My trail boss, 223 subsonic loads, shot like crap. My Blue Dot loads do much better

I lost my notes in a fire a while back but it seems like I wound up around 10 grs BD with the 69 Sierra in my 223,, I might try working down from about 17 grs in the 22 ARC and see how it goes, I bet it would wind up at about 11.5-12 but was hoping somebody else had already tried this. Lol
